HORSESHOE-NAIL CLENCHER.

SPECIFICATION forming part Of Letters Patent NO. 570,185, dated October27, 1896. Application filed July 10, 1896. Serial No. 598N752. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, J OSEPH l-I. RANCK, a citizen of the United States,residing at Hustontown, in the county of Fulton and State ofPennsylvania, have invented certain new and useful Improvements inHorseshoe-Nail Olen chers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to horseshoe nail clenchers.

My object is to provide a simple, cheap, and extremely powerfulnail-clencher of the class described which will be adapted for quick andeasy application and manipulation to clench the nail in a highlysuperior manner without injuring the hoof.

Having this object in view, my invention consists of a clencher ofimproved construction, as will appear more fully hereinafter,

and in the accompanying drawings,in which- Figure 1 is a perspectiveview showing my improved nail-olencher in use, and Fig. 2 shows alongitudinal section of the tool.

The numeral 1 designates a handlever which is provided at one end with ajaw 2. This lever is bent to form an open handle 3, having a partition4. There is a rockinglever which consists of two curved sections 5 and6, which are connected byapin 7. The sections are provided with curvedslots 8, which terminate in straight slots 9, said slots being locatedin alinement. ver 1 projects between the sections of the rocking lever,and 10 designates a pivot-bolt which passes through the hand-lever andslots in the rocking lever. Owing to this construction the point ofpivotal connection between the rocking lever and the hand-lever can bechanged by shifting the latter, so that the pivot-bolt will either lieat the bottom of the curved slots or at the bottom of the straightslots.

The numeral 11 designates a plunger which works through the forward endof the handle of lever 1, and also through the partition of said handle.This plunger is provided with an adjusting-nut 12, and between this adjusting-nut and a nut 13 loose on the plunger The forward end of lethereis located a coil-spring 14, which tends 'to keep the plunger retractedin the handle and the adjusting-nut abutting on the partition of thelatter. A pitman 15 is pivotally connected to the forward end of theplunger and is also pivoted on a bolt 16, which passes through the lowerends of the respective sections of the rocking lever. Thus the upper endof the rocking lever is normally thrown forward so that it overhangs thejaw of the hand-lever.

A clenching-dog 17 is pivoted between the sections of the rocking leverand on a bolt 18, and is provided with a foot 19, having serrations onits bottom, said foot lying immediately above the jaw 2 of thehandle-lever 1.

Then this dog is depressed, it abuts on the pin that connects thesections of the rocking lever. A second hand-lever 20 is pivoted betweenthe sections of the rocking lever on a bolt 21, which extends throughthe extreme upper end of the latter. Two links 22 straddle thishand-lever and the dog, and are pivotally connected thereto byrespective bolts 23 and 24c.

The operation is asfollows: After the nail has been driven through theshoe and hoof the jaw of said hand-lever 1 is passed under the shoe sothat it abuts on the head of the nail to be clenched. The spring holdsthe foot of the dog pressed against the side of the hoof so that the jawis held firmly against the head of the nail. The hand-lever 20 shouldnow be raised, and when this is done the dog is actuated and its footpressed upon the point of the nail, whichprotrudes through the hoof,bending the nail over and clenching it inward into the hoof. If theclench is to be made higher up than usual, the pivotbolt of hand-lever 1may be shifted so that it will lie at the bottom of the curved slots.The before-described operation may now be repeated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a horseshoe-nail clencher, the combination with a hand-leverprovided with a jaw, of a rocking lever pivoted to the hand-lever, aspring-pressed plunger working in the handlever and pivotally connectedto the rocking IOO lever, a elenchingdog also pivoted to the rockinglever, and means for actuating said dog.

2. In a horseshoe-nail clencher, the combination with a hand-leverprovided with a jaw, of a rocking lever pivoted to the hand-lever, aplunger working in the hand-lever, a link pivotally connecting theplunger to one end of the rocking lever, a plunger-actuated coilspringencircling the plunger, a clenchingdog pivoted to the free end of therocking lever, and means for actuating said dog.

In a horseshoe-nail clencher, the combination with a hand-lever providedwith a jaw, of a spring-retracted rocking lever pivoted to thehand-lever, a clenching-dog provided with a foot and pivoted to therocking lover, a second hand-lever also pivoted to the rocking lever,and a link pivotally connecting the clenching-dog with the secondhand-lever.

4. 111 a horseshoe-nail elencher, the combination with a hand-leverprovided with a jaw, of a rocking lever adjustably fulcrulned to thehand-lever, a clenching-dog pivotally connected to the rocking lever,and means for actuating the dog.

5. In a horseshoe-nail clencher, the combination with a hand-leverprovided with a jaw, of a rocking lever provided with a curved and astraight slot in communication, a pivoted bolt passing through thehand-lever and the slot in the rocking lever, a clenching-dog pivoted tothe rocking lever, and means for actuating said dog.

0. In a horseshoe-nail clencher, the combination with a hand-leverprovided with a jaw, of a rocking lever adjustably fulcrumed to thehand-lever, a spring-pressed plunger movable in the hand-lever andpivoted to the rocking lever, a clenching-dog having a foot and pivotedto the rocking lever, a second hand-lever also pivoted to the rockinglever, and a link pivotally connecting the second hand-lever with thedog.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JOSEPH I-I. RANOK.
